The survivors of the “Precipitation at the Entrance” split into two major factions. The first faction believed that the disaster was all planned by heaven’s gods. On the other hand, the second faction believed that anything in the human world had a scientific explanation for it, and they proposed a theory that there exists a more balanced world, a utopia. The two factions rejected each other, argued with each other, and started killing each other. This phenomenon drew the human world closer and closer to a second disaster.
